Answer: A

Explanation:

The recommended longest lancet for taking a blood sample from the heel of a newborn baby is 2.4 mm.

Care should be taken not to take the sample from the back of the heel where the distance from the skin surface to the bone can be as little as 2.33 mm. If in doubt, or if the child is premature or underweight, use a smaller lancet.
